Windows Installer - Another version of this product already exists [duplicate]

Question

This question already has an answer here:

Creating an updateable setup using Install Shield that ships with VS2012 (1 answer)

Closed 8 years ago.

I've asked this question already and can't believe that no one has an answer and I write it again in a different way to see if anyone can lend a hand.

When I create the second version of my winforms app and configure InstallSheild LE to install it, all seems to be straightforward.

When I then run the install I go through a couple of screens and then a popup appears stating:

"Another version of this product exists....Use Add/Remove programs on control panel"

Can anyone confirm if the LE version of InstallShield that is freely available for VS2012 will create an update installation that doesn't require the removal of the current version, or do I need a paid for version to get this basic functionality?

Thanks,

Jason.

Answer 1

You need to change the PackageCode and the ProductCode to make the installer think it's a completely new install.

I'm not sure where that will be in InstallShield (I don't use it).
